Standard Specification for Preformed Polychloroprene Elastomeric Joint Seals for Concrete Pavements

Standard Specification for Preformed Polychloroprene Elastomeric Joint Seals for Concrete Pavements

ABSTRACT
This specification covers the material requirements for preformed polychloroprene elastomeric joint seals for concrete pavements. The seal consists of a multiple web design and is installed with a lubricant. The seal functions by compression of the seal between the faces of the joint with the seal folding inward at the top to facilitate compression. The seals shall be preformed, and the material shall be vulcanized elastomeric compound using polychloroprene as the only base polymer. The materials shall also comply with the physical properties prescribed herein such as tensile strength, elongation, hardness, oil swell, ozone resistance, low-temperature stiffening, low-temperature recovery, and compression deflection.
SCOPE
1.1 This specification covers the material requirements for preformed polychloroprene elastomeric joint seals for concrete pavements. The seal consists of a multiple web design and functions only by compression of the seal between the faces of the joint with the seal folding inward at the top to facilitate compression. The seal is installed with a lubricant and is designed to seal the joint and reject incompressibles.
1.2 The values stated in inch-pound units are to be regarded as standard. 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 the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
Note 1—This specification is a manufacturing and purchasing specification only and does not include requirements or considerations for selection of size, or the installation of the joint seals. However, experience has shown that successful performance of this product depends upon the proper selection of size and cross-sectional design of the joint seal, joint size, and joint spacing for the ambient conditions the pavement will be exposed to, and care in the installation of the joint seals.

ASTM D2950/D2950M-22(Test Method)
Standard Test Method for Density of Asphalt Mixtures in Place by Nuclear Methods

SIGNIFICANCE AND USE
4.1 The test method described is useful as a rapid, nondestructive technique for determining the in-place density of compacted asphalt mixtures.  
4.2 With proper calibration and confirmation testing, the test method is suitable for quality control and acceptance testing of compacted asphalt mixtures.  
4.3 The test method can be used to establish the proper rolling effort and pattern to achieve the required density.  
4.4 The nondestructive nature of the test allows repetitive measurements to be made at a single test location between roller passes and to monitor changes in density.  
4.5 The density results obtained by this test method are relative. Correlation with other test methods such as D1188/D1188M, D2726/D2726M, or D6752/D6752M is required to convert the results obtained using this method to actual density. It is recommended that at least seven core densities and seven nuclear densities be used to establish a conversion factor. A new factor must be established at any time a change is made in the paving mixture or in the construction process.
Note 1: The quality of the results produced by this standard are dependent on the competence of the personnel performing the procedure and the capability, calibration, and maintenance of the equipment used. Agencies that meet the criteria of Specification D3666 are generally considered capable of competent and objective testing, sampling, inspection, etc. Users of this standard are cautioned that compliance with Specification D3666 alone does not completely ensure reliable results. Reliable results depend on many factors; following the suggestions of Specification D3666 or some similar acceptable guideline provides a means of evaluating and controlling some of those factors.
SCOPE
1.1 This test method describes a test procedure for determining the density of asphalt mixtures by the attenuation of gamma radiation, where the source and detector(s) remain on the surface (backscatter method) or the source or detector is placed at a known depth up to 300 mm [12 in.] while the detector or source remains on the surface (direct transmission method).  
1.2 The density, in mass per unit volume of the material under test, is determined by comparing the detected rate of gamma emissions with previously established calibration data.  
1.3 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 nonconformance with the standard.  
1.4 All observed and calculated values shall conform to the guide for significant digits and rounding established in Practice D6026.  
1.5 For limitations, see Section 5 on Interferences.  
1.6 The text of this standard references notes and footnotes which provide explanatory material. These notes and footnotes (excluding those in tables and figures) shall not be considered as requirements of the standard. It is the recommendation of Committee D04 that the following note be added to the end of the Significance and Use section of all applicable standards. Applicable standards are those in which measurement or calibration are made, sample are procured, or products are selected. The subcommittee shall determine the appropriateness of adding the note throughout the consensus process.  
1.7 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. For specific warning statements, see Section 7.

Standard Classification for Hot-Mix Recycling Agents

SIGNIFICANCE AND USE
3.1 Recycling of deteriorated asphalt pavements is being used with increasing frequency for its economy and benefit of conserving raw materials. The objective of recycling is to reuse the two ingredients of asphalt concrete-aggregate and asphalt binder and to restore the desired properties to the mixture. Recycling is carried out hot or cold, depending on the condition of the deteriorated pavement, construction procedure, availability of equipment, and cost. This classification is for classifying recycling agents to be used in recycled asphalt mixtures.  
Note 3: The quality of the results produced by this standard are dependent on the competence of the personnel performing the procedure and the capability, calibration, and maintenance of the equipment used. Agencies that meet the criteria of Specification D3666 are generally considered capable of competent and objective testing, sampling, inspection, etc. Users of this standard are cautioned that compliance with Specification D3666 alone does not completely ensure reliable results. Reliable results depend on many factors; following the suggestions of Specification D3666 or some similar acceptable guideline provides a means of evaluating and controlling some of those factors.
SCOPE
1.1 This standard covers a standardized method whereby recycling agents to be used in hot recycling of asphalt concrete can be classified. The recycling agents are classified by viscosity in mm2/s measured at 60 °C [140 °F]. This classification does not apply to emulsified recycling agents.  
1.2 This standard does not address the performance of asphalt binder blends with recycling agents, or that of hot-mix asphalt mixture containing recycling agents. Adherence of a recycling agent to this specification does not necessarily relate to the performance of asphalt binders and mixtures containing the recycling agents.
Note 1: The impact of recycling agents has been evaluated by extracting the asphalt binder from the pavement to be recycled, and combining with the recycling agent to meet the appropriate grade within Specification D946/D946M or Table 1, 2, or 3 of Specification D3381/D3381M. More recently, some specifications have referred to performance grading as described in Specification D6373 or D8239.
Note 2: Efforts are underway to utilize performance-based testing of the asphalt mixture containing recycling agents as a measure of compliance.  
1.3 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 nonconformance with the standard.  
1.4 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.  
1.5 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.
