Struktur jalan paling akhir menerima beban pada konstruksi jalan adalahtanah dasar. Kemampuan tanah dasar (daya dukung) dapat diperoleh darihasil pemeriksaan California Bearing Ratio (CBR) laboratorium ataupun dariCBR lapangan. Permasalahan yang sering dihadapi terutama jalan diProvinsi Riau khususnya pekanbaru tanah dasar merupakan tanah lunakberupa lempung dengan plastisitas tinggi. Salah satu cara untukmeningkatkan daya dukung tanah dasar tersebut menggunakan metodestabilisasi tanah dengan aspal emulsi. Penelitian ini bertujuan untukmengetahui nilai karakteristik tanah dasar lempung organik denganplastisitas tinggi (CH) berdasarkan Unified Soil Clasification System (USCS).Stabilisasi menggunakan aspal emulsi jenis Cationik Rapid Setting (CRS)dengan variasi penambahan 4%, 6%, 8% dan 10%. Hasil pengujian diperolehnilai CBR tertinggi pada penambahan kadar aspal emulsi 8% sebesar 6,05%.Pengujian terhadap kuat tekan bebas diperoleh pada penambahan aspalemulsi kadar 10% sebesar 0,174 MPa. Hasill pengujian yangdirekomendasikan untuk tanah lempung organic dengan plastisitas tinggiadalah pemakaian kadar aspal 8%, dengan nilai CBR 6,05% dan UCS 0,141MPa.

Rapid Setting

Rapid setting and low viscosity of sulphoaluminate cement (SAC) make it difficult to be extruded by 3D printing (3DP) technique. In this study, the effect of tartaric acid (TA) on printability, rheology and mechanical property of 3DP SAC paste is investigated. The experimental results indicate that the setting time, hydration evolution and apparent viscosity of SAC paste can be well controlled by adding a proper amount of TA to satisfy the requirements of 3DP. An excellent structure of SAC paste with the ultimate deformation rate less than 10% can be printed without compromising mechanical strength.
