Natural Construction Materials for Road Construction: A Case Study in Ninh Thuan Province, Viet Nam

The article mentions the formation characteristics and the possibility of using natural mineral construction materials in road construction in Ninh Thuan province. Research results show that Ninh Thuan has quite rich sources of natural construction materials. Natural construction stone materials include intrusive rocks of the Deo Ca, Dinh Quan, Ca Na complexes, eruptive rocks of the Don Duong and Bao Loc Pass formations, terrigenous sediments of the La Nga formation. Natural construction soil materials include a group of relict soils weathered from different rocks, and soils of alluvial origin (a), mixed alluvial deposits (a, ap), and marine (m) sediments. According to the potential reserves and quality of construction rocks, they can be classified in descending order into intrusive rocks, extrusive rocks, and continental sedimentary rock; Soil types according to potential reserves can be ranked as apQ soils, eQ soils formed by extrusive rocks and eQ soils formed by intrusive rocks.
