摘　　要：使用高模量沥青混凝土可以解决大多数高速公路沥青路面在使用早期就出现车辙病害的问题。结合本-辽-辽高速公路的工程实际,介绍掺加"路宝牌"高模量外掺剂的中面层LAC-20I型沥青混合料的室内试验和现场施工情况,实践表明,高模量沥青混凝土具有施工方便、高温性能好、造价低等特点。Applying high -modulus asphalt concrete might solve early diseases problems of asphalt pavement of majority of freeways. In the light of engineering practice of Ben - Liao - Liao freeways, the paper introduces indoor test and site construction of LAC - 20 Type asphalt mixture for intermediate surface which high - modulus admixture of ＂Lubaopai＂ brand have been admixed into. Practice states clearly that high - modulus asphalt concrete possesses the features of convenient construction, good high - temp performance and less cost.
