NCHRP Web-Only Document 376: Rapid Tests and Specification Language for Construction of Asphalt-Treated Cold Recycled Pavements, from TRB's National Cooperative Highway Research Program, provides the results and analysis of field testing conducted to verify the short-pin raveling test (SPRT) and long-pin shear test (LPST) threshold values recommended in NCHRP Research Report 960: Proposed AASHTO Practice and Tests for Process Control and Product Acceptance of Asphalt-Treated Cold Recycled Pavements. Revised test threshold values were developed and are also presented in this report.
A training video is available to assist operators with properly conducting the tests.
