This paper presents an extensive series of laboratory works and a prediction model on the design road pavement subgrade with Xanthan Gum (XG) biopolymer. The experimental were carried out using mixtures conventional aggregate for construction XG at ratios 0%, 1%, 2%, 5%, by dry weight. Unconfined compressive strength (UCS) California bearing ratio (CBR) tests conducted during end various curing...

Sifat tanah dasar berperan penting untuk konstruksi jalan. Tanah bisa berupa timbunan yang dipadatkan. fisis dan mekanis merupakan nilai atau parameter melihat syarat kwalitasnya. Tujuan penelitian ini adalah menentukan karakteristik sebagai subgrade. Metode digunakan pengujian laboratorium mendapatkan sifat timbunan. Sampel diambil dari Tenayan Raya, Kulim Kota Pekanbaru. Hasilnya klasifikasi ...

In the alpine mountain area, stability of steep-slope permafrost subgrade is mainly affected by temperature variation in frozen soil layer at base road. Under conditions climate warming and engineering-related disturbance, cooling an urgent problem to be solved field construction. this paper, numerical calculation method, combined with data monitored situ, used study effects several measures, w...
