聚乙烯改性沥青NOVOPHALT在机场道面上的应用及探讨

THE APPLICATION STUDY OF THE POLYETHYLENE MODIFIED ASPHALT-NOVOPHALT IN THESURFACE OF AIRPORT RUN-WAY

某军民两用机场引进奥地利ＮＯＶＯＰＨＡＬＴ铺筑技术对茂名７０号沥青进行改性．用以加盖该机场道面，该工程分底、中、面三层铺筑．总厚度为１８ｃｍ．三层累计作业总面积为３４３０００ｍ２．沥青砼总量为４６５８２ｔ。铺筑后的道面经过一年多的使用．目前没有发现轮辙、拥包、松散、裂纹现象．

Maoming No.70 asphalt was modified with Austria's NOVOPHALT and paved in the surface of runway in an army-People airport.Three layers were paved,the sum of thickness was 18cm,the sum of paving area of three layers was 343000m2,and the sum of asphalt mixture was 46582t0 even though it had been put into service over a year,the rut、shoving、ravelling and crack have still not been produced on the surface of the run-way.
