Abstract

Recycling technology or Cement Treated Recycling Base (CTRB) is one method for repairing damage to ancient road pavements, however, when the process is in place (Mixed in place), difficulties can arise, such as mixing with existing soil material that shouldn't be mixed in its implementation. because this will affect the results of Unconfined Compressive Strength (UCS). As a binder in the form of local cement from South Kalimantan, the brand is cheaper because production costs are cheaper. This study aims to obtain UCS Results at minimal cement levels that still meet the requirements with the use of brand local cement, obtain the typical influence of existing soil on UCS and what percentage of existing soil material can still be tolerated either curing or non-curing and correlation and get recommendations for the maximum percentage of influence of percent of existing land on UCS in curing or non-curing conditions. RAM samples were obtained for the purpose of investigation, which was done in a lab, existing soil and additional materials in the field. Inspection of old aggregates, making test specimens with variations in cement content of 1-10%, after obtaining minimum UCS according to technical requirements then making test specimens with variations in soil examinations and soil content of 0%, 5%, 10%, 15%, 20%, and 25% again then conducting data analysis to find correlations / relationships. The results of the research showed variances in cement content of 1% (one) - 10% that still meet the technical specifications of UCS (at least 30 kg/cm²) obtained a minimum cement content of 5% (five percent) with a UCS of 33.77 kg/cm². Then the test results of the influence of existing soil on UCS that is still tolerated are mixed, namely in curing conditions is 17% with the equation Y = -0.10075 x + 46.894 (R2 = 0.964). and non-curing 8.9% with the equation Y = -0.1113 x + 39.814 (R2=0.956). The R2 conclusions for both indicate a very There is a substantial correlation between the two factors

既有土对水泥处理再生基(CTRB)型柔性路面无侧限抗压强度(UCS)的影响

回收技术或水泥处理回收基地(CTRB)是修复古路面损坏的一种方法，然而，当这个过程到位(混合到位)时，可能会出现困难，例如在实施过程中与现有的不应该混合的土壤材料混合。因为这将影响无侧限抗压强度(UCS)的结果。作为南加里曼丹当地水泥形式的粘合剂，该品牌价格较低，因为生产成本较低。本研究旨在通过使用本地品牌水泥，获得在最低水泥水平下仍能满足要求的UCS结果，获得现有土壤对UCS的典型影响，以及在固化或不固化条件下仍能容忍的现有土壤材料的百分比和相关性，并获得在固化或非固化条件下现有土地百分比对UCS的最大影响百分比的建议。为了进行调查，在实验室、现场现有土壤和其他材料中获得了RAM样本。对旧骨料进行检验，制作水泥含量变化1-10%的试样，根据技术要求获得最小UCS后，再制作土壤检查变化的试样，土壤含量分别为0%、5%、10%、15%、20%、25%，然后进行数据分析，寻找相关性/关系。研究结果表明，水泥含量在1%(1)- 10%的变化范围内，仍然符合UCS的技术规范(至少30 kg/cm²)，水泥含量最低为5% (5%)，UCS为33.77 kg/cm²。然后将现有土对仍可耐受UCS影响的试验结果进行混合，即在养护条件下为17%，方程为Y = -0.10075 x + 46.894 (R2 = 0.964)。非固化8.9%，方程Y = -0.1113 x + 39.814 (R2=0.956)。两者的R2结论都表明两个因素之间存在很大的相关性
