Description

一种评价沥青混合料沥青用量的试验方法 技术领域
本发明涉及沥青技术领域,尤其涉及一种评价沥青混合料沥青用量的试验方法。
背景技术
目前,在沥青混合料的沥青用量上有两个计算方法一是沥青油膜厚度计算,按混合料组成级配,计算比表面积,按经验的沥青油膜厚度计算沥青用量阈值,二是粉胶比计算,沥青混合料中,0.075mm筛孔通过率与沥青用量的比值,在Suppaper设计方法中,规定了粉胶比0.6~1.6。
但是按一沥青油膜厚度计算出的沥青用量阈值,由于集料密度不同、吸水率不同,油膜厚度本身也是经验值,采用多种变量和模糊数值确定沥青用量的阈值,本身存在不局限性。
按二“粉胶比”来作为评判的依据之一,也是不科学的,粉胶比范围太宽范,且沥青混合料的用油用与集料自身物理特性、级配组合有很大关系,粉胶比不能反应这些性质,存在局限性,为此,我们提出了一种评价沥青混合料沥青用量的试验方法来解决上述问题。
发明内容
本发明的目的是为了解决现有技术中存在的缺点,而提出的一种评价沥青混合料沥青用量的试验方法。
为了实现上述目的,本发明采用了如下技术方案:
一种评价沥青混合料沥青用量的试验方法,包括以下步骤:
S1、准备析漏试验机、析漏试筒、玻璃板、小型沥青混合料拌和机、手铲、天平和棉纱实验工具;
S2、按沥青等粘温度试验,确定拌和温度进行析漏试验;
S3、在洗净、烘干的析漏试筒中,称取析漏试筒m 0,准确至0.01g,放入试验箱进行恒温,恒温时间不少于2小时;
S4、根据实际使用的沥青混合料的配合比,对集料、矿粉、沥青、纤维稳定剂等按照T0702的方法用小型沥青混合料拌和机拌和混合料,拌和时纤维稳定剂在粗细集料加入后加入,并适当干拌分散,再加入沥青拌和至均匀,每次拌和只能拌和一个试件,一组试件分别拌和4份,每1份约为1kg,第1锅拌和后即予废弃不用,使拌和锅黏附一定量的沥青结合料,以免影响后续3个试样油石比的准确性,当为施工质量检验时,直接从拌和机中取样;
S5、将拌制的沥青混合料装入析漏试筒内,称取析漏试筒及混合料的总质量m 1,准确至0.01g,将析漏试筒装入试验箱旋转笼内进行固定,并在试验箱设定恒温环境下,静置2小时。
S6、启动试验箱,以30r/min的旋转速率,匀速旋转至1000r停止;
S7、取出析漏试筒,不加任何冲击或振动,将混合料向下倒扣在玻璃板上,利用手铲棉纱等将混合料放置到天平上,称取析漏试筒以及黏附在析漏试筒上的沥青结合料、细集料、玛蹄脂等的总质量m 2,准确至0.01g;
S8、利用
Figure PCTCN2020095017-appb-000001
进行沥青析漏损失计算;
S9、试验至少进行平行试验3次,然后取平均值作为试验结果。

本发明的试验方法将一定量的沥青混合料放入试验装置中,在规定的温度下保温一定时间,以规定的转运速率转运规定的次数,倒出沥青混合料,测定滚筒内沥青析漏的质量及百分比,用以检测沥青结合料在高温状态下从沥青混合料中析出多余的自由沥青数量,供进行检验沥青玛蹄脂碎石混合料(SMA)、排水式大空隙沥青混合料(OGFC)或沥青碎石类混合料的最大沥青用量时使用。
