ASTM D7942-15(2023)(Specification)
Standard Specification for Thermoplastic Pavement Markings in Non Snow Plow Areas

ABSTRACT
This specification covers reflectorized thermoplastic based pavement striping material of the class that is applied to the road surface in a molten state by screed/extrusion or ribbon extrusion means. It deals with longitudinal applications in non snow plow areas, standard (non-profile) pavement marking applications, and applications on smooth asphalt or concrete surfaces. It does not include asphalt seal coat applications, which use large aggregate resulting in a very rough, open grade finish. This specification establishes requirements with respect to chemical composition and physical property of the thermoplastic pavement marking material, requirements for the optics that are used to reflectorize the thermoplastic pavement marking material after application, field performance requirements for the installed thermoplastic pavement markings, and material application requirements.
SCOPE
1.1 This specification covers a reflectorized thermoplastic-based pavement striping material of the class that is applied to the road surface in a molten state by screed/extrusion or ribbon extrusion means. Retroreflectivity of the pavement marking compound is achieved initially by surface application of retroreflective optics at the time of pavement marking application. Upon cooling to normal pavement temperature, the pavement marking material produces an adherent reflectorized stripe of specified thickness and width capable of resisting deformation by traffic. The pavement marking compound includes retroreflective optics (glass beads or composite optics, or both) that are incorporated into the material at the time of manufacture that provide retroreflective properties during the service life of the material.  
1.1.1 This specification is limited to:
1.1.1.1 Longitudinal applications in non snow plow areas,
1.1.1.2 Standard (non-profile) pavement marking applications, and
1.1.1.3 Applications on smooth asphalt or concrete surfaces. Asphalt seal coat applications, which use large aggregate resulting in a very rough, open grade finish, are excluded from this specification.  
1.1.2 This specification includes:
1.1.2.1 Compositional and physical property requirements of the thermoplastic pavement marking material,
1.1.2.2 Requirements for the optics that are used to reflectorize the thermoplastic pavement marking material after application,
1.1.2.3 Field performance requirements for the installed thermoplastic pavement markings, and
1.1.2.4 Material application requirements.  
1.2 The values stated in inch-pounds units are to be regarded as the standard except where noted in the document. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.  
1.3 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.  
1.4 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

ASTM
ASTM F2656/F2656M-23(Test Method)
Standard Test Method for Crash Testing of Vehicle Security Barriers

SIGNIFICANCE AND USE
5.1 This test method provides a structured procedure to establish a penetration rating for vehicle perimeter barriers subjected to a vehicle impact. Knowing the penetration rating helps to select an appropriate barrier for site-specific conditions around a facility.  
5.2 The barrier penetration rating does not imply that a barrier will perform as rated in all site conditions, approach routes, and topography. Also, only single-specimen tests at a specified impact location are required by this test method, and therefore, not all points of impact can be tested and validated for the penetration rating. Other impact locations may respond differently.
SCOPE
1.1 This test method provides a range of vehicle impact conditions, designations, and penetration performance levels. This will allow an agency to select passive perimeter barriers and active entry point barriers appropriate for use at facilities with a defined moving vehicle threat. Agencies may adopt and specify those condition designations and performance levels in this test method that satisfy their specific needs. Agencies may also assign certification ratings for active and passive perimeter barriers based on the tests and test methodologies described herein. Many test parameters are standardized to arrive at a common vehicle type and mass, and replication, and produce uniform rating designations.  
1.2 Compliance with these test procedures establishes a measure of performance but does not render any vehicle perimeter barrier invulnerable to vehicle penetration. Caution should be exercised in interpreting test findings and in extrapolating results to other than test conditions and to user site conditions. This standard does not confirm the performance of the test barrier in the user site conditions. While computer simulations are powerful tools that are useful in the development of new and improved barriers or in estimating performance under differing conditions, the analytical models and methods must be validated against physical test data. When performing a test, developers and users are encouraged to address specific or unusual user site conditions as needed.  
1.2.1 Often local terrain features, soil conditions, climate, or other items will dictate special needs at specific locations. Therefore, if user site conditions are likely to degrade a barrier’s performance, the agency in need of a vehicle perimeter barrier should require testing with the specific user site conditions replicated for full-scale crash testing or numerical simulations that explicitly represent the user site conditions and have demonstrated connection to the “as-tested” soil configuration. For example, if the user site conditions are expansive clays, one could obtain user site materials and provide those to the test lab for the full-scale crash test.  
1.3 Product/design certification under this test method only addresses the ability of the barrier to withstand the impact of the test vehicle. It does not represent an endorsement of the product/design or address its operational suitability.  
1.4 The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in non-conformance with the standard.  
1.5 This test method is intended to replace all previous versions of the test method for current and future testing.  
1.6 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and to determine the applicability of regulatory limitations prior to use.  
1.7 This international standard was developed in accordance with internationally recognized principles on standardization established ...

Standard Practice for Conducting Road Service Tests on Fluid Traffic Marking Materials

SIGNIFICANCE AND USE
3.1 This practice is an accelerated evaluation of bead retention, retroreflectivity, daytime color, night time color, and wear characteristics of fluid traffic marking materials. It is used to determine the useful life of such markings in the field. The same procedures are applicable to evaluating longitudinal lines to determine service life.
SCOPE
1.1 This practice covers the determination of the relative service life of fluid traffic marking materials such as paint, thermoplastic, epoxy, and polyester products under actual road conditions using transverse test lines. Materials under test are applied under prescribed conditions and periodic observations are made using prescribed performance criteria.  
1.2 The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information only.  
1.3 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.  
1.4 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

ASTM D711-23(Test Method)
Standard Test Method for No-Pick-Up Time of Pavement Markings

SIGNIFICANCE AND USE
3.1 This test method serves as a laboratory control test. Types of pavement markings that can be tested with this method are waterborne traffic paint, solvent borne traffic paint, and some two component 100 % solids liquid pavement markings, such as epoxy and modified epoxy pavement markings. If wet film thickness, temperature, and humidity are controlled within the tolerances specified herein, this method can be useful for relative testing of pavement markings and potentially for qualification of pavement markings for field application in approved specifications. For improved repeatability and meaningful comparison of pavement markings samples being tested, consistent air flow over the pavement marking films during testing is important. The buyer and seller should agree upon the air flow conditions, whether it be static or carefully regulated air flow (see 4.6.1 and 4.6.2). Because of the many variables operative in the field application of pavement markings (for example, wet film thickness, air temperature, humidity, wind speed, pavement type (asphalt or concrete), film profile over pavement, pavement temperature, pavement porosity, pavement moisture content, and the presence or absence of direct sunlight during striping), a direct correlation between the results of this test and field applications is difficult to obtain. However, relative field performance can be predicted using this method if the testing protocol is adhered to. For testing of two component 100 % solids liquid pavement markings an application of drop on retroreflective optics are typically applied at a specified rate to the markings prior to testing. For these types of pavement markings the regulation of air flow is not necessary due to the drying mechanics of the product.
SCOPE
1.1 This test method covers a laboratory procedure for determining the no-pick-up time of pavement markings. The method uses a wheel consisting of a metal cylinder with rubber O-rings. The wheel is rolled down a ramp over a freshly applied pavement marking film repeatedly until there is no transfer of the marking material to the rubber rings. The elapsed time from pavement marking film application to point of no marking material transfer is the no-pick-up time. Key variables to be controlled during testing are wet film thickness, temperature, humidity, air flow, and use of retroreflective optics. This standard provides three options for the testing of the no-pick-up time for pavement markings. The first option, Method A, specifies controls for temperature, humidity, and air flow during testing; a second option, Method B, specifies controls for temperature and humidity during testing, and a third option, Method C, provides guidance for performing this with a drop on application of retroreflective optics such as glass beads, Waterborne and Solvent Borne pavement markings are typically tested using Procedure A or Procedure B, without the application of drop on retroreflective optics. Pavement markings that are two component 100 % solids are typically tested using Method C.  
1.2 The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information only.  
1.3 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.  
1.4 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
