Preventive Maintenance Condition Standards of Expressway Asphalt Pavement
There isnt a unified pavement preventive maintenance road condition standard both at home and abroad till now, in view of that, macro and micro road condition standard for expressway asphalt pavement preventive maintenance is established, among which macro standard is under the promise of PSSI≥83, and is under the control standard of 82≤PCI<88, 88≤RQI<93, 85 ≤SRI<90. Its determinative process, the usage and application are introduced. Researches show that the macro standard established can meet the concept and characteristics of preventive maintenance, which is suitable both in high and low level, and the range, combining with the micro standard, it is beneficial to discriminate whether pavement preventive maintenance is suitable.
