T/CHCA 017-2023 Road engineering technical specification for application of rock asphalt
Basic Information
Scope
Main technical content: This specification fully summarizes and absorbs the research results and successful experiences of domestic rock asphalt and rock-modified asphalt, and proposes technical requirements mainly from aspects such as raw materials, mix design, and construction. It widely solicited opinions and suggestions from construction, maintenance, design, and scientific research units, and conducted special research on the performance of rock asphalt, giving full consideration to the coordination and consistency with other relevant standards. This specification was drafted in accordance with the "Guide for the Preparation of Highway Engineering Industry Standards" (JTG 1003—2023) and is divided into 5 chapters and 1 appendix, namely: 1 General Provisions; 2 Terms and Symbols; 3 Raw Materials; 4 Mix Design; 5 Construction; Appendix A: Penetration Test Method for Rock Asphalt
