Engineering Properties of Highway Materials in Songkhla Province

Abstract

Songkhla is a province with a lot of crushed stone and laterite. Both materials are the main materials used by the Department of Highways or other agencies in road construction. Testing the engineering properties of the materials used in road construction are sieve analysis, abrasion, atterberg limit test, compaction and California bearing ratio test. The test results obtained will be compared with the standard values of the Department of Highways. This article will study and test to determine the engineering properties of engineering materials, guidelines for improving the soil to be suitable for use and the tendency of material shortages in the area. After that, a database was created to publish on the Internet. To be a guideline for responsibly choosing construction materials from various sources in Songkhla province and increasing the efficiency of material use in road construction.
