Method for determining formula of high-modulus anti-fatigue hot recycled asphalt mixture
The invention provides a method for determining a formula of a high-modulus anti-fatigue thermal regeneration asphalt mixture. The method comprises the following steps: S10, measuring the proportion of old asphalt in RAP divided into n grades and the PG high-temperature grade; s20, selecting new asphalt; s30, setting the ratio of each grade of RAP in the reclaimed material; s40, performing grading design on the new aggregate, the new filler and the mineral aggregate in each grade of RAP according to the ratio of each grade of RAP in the reclaimed material, judging whether the requirements can be met or not, if so, executing the step S50, and if not, repeating the steps S30-S40; and S50, substituting the proportion and the PG high-temperature grade of the old asphalt in the RAP, the PG high-temperature grade of the new asphalt and the proportion of each grade of RAP in the reclaimed material into a formula, and judging whether the formula is met or not. And S50, determining the asphalt content in the hot recycled asphalt mixture on the basis of the RAP and the new asphalt when the RAP and the new asphalt meet the requirement, so as to obtain a recycled material formula, and repeating the steps S20 to S50 when the RAP and the new asphalt do not meet the requirement.
本公开提供一种确定高模量抗疲劳热再生沥青混合料配方的方法，包括：S10测定在分成n档的RAP中旧沥青的占比和PG高温等级；S20选择新沥青；S30设定在再生料中各档RAP占比；S40根据再生料中各档RAP占比，对新集料、新填料和各档RAP中的矿料进行级配设计，判断是否能够满足要求，如果能够，执行步骤S50，如果不能，重复步骤S30～S40；和S50将RAP中旧沥青的占比和PG高温等级、新沥青的PG高温等级、再生料中各档RAP占比代入公式，判断是否满足该公式。当满足时，基于所述RAP和所述新沥青，确定所述热再生沥青混合料中的沥青含量，得到再生料配方，当不满足时，重复步骤S20～S50。
