Abstract:Fiberglass geogrids are often used to minimize thermal and stress related reflective cracking and to increases the fatigue life of pavements with weak foundations. The objective of this paper is to evaluate the bearing capacity of flexible pavement system on weak subgrade reinforced with fiberglass geogrids by laboratory California Bearing Ratio (CBR) test. The pavement system consists of a cold mix asphalt layer, a gravel base layer, and a soft clay subgrade. Two fiberglass geogrids were used as reinforcement… Show more
