On site Test of FDR Gradation of FDR base layer: The gradation of the in-situ pulverized materials should meet the criteria given in MoRD specifications as presented in Table 1. However, if the gradation obtained is different, then additional material of desired sizes shall be mixed and mix design can be done subjected to meet the desired gradation, strength, and durability criteria. . A well graded mixture is critical to ensure the FDR layer will be strong and durable with the minimum amount of cement. Before pulverization: The gradation of existing base is done before pulverization, if the gradation obtained is different, then additional material of desired sizes shall be mixed to obtain aggregate soil ratio as per mix design/Job Mix Formula (JMF). Test format of before gradation is given below: PROJECT: Client: Contractor: Sieve Analysis (FDR Mix) Package No./ Road Name: Chainage/Location
