Evaluation on properties of tender mixes

Tender mix has caused many problems to the contractor during the construction of hot mix asphalt (HMA) pavement. The objective of this paper was to investigate the properties of tender mixes as related to the problem of rutting. Two mixes of ACW20 were designed in compliance to Jabatan Kerja Raya (J...
