Optimization of Standard Mix Design of Porous Paving Coconut Fiber and Shell for The Parking Area
Daftar Isi:
- The pavement in the parking area is usually concrete paving with class B quality with a flat surface appearance, no cracks, and defects, minimum thickness of 60 mm with a tolerance of ± 8%. The condition of parking area infrastructure which in the rainy season occurred water puddles which is a common problem that arises this is due to high rainfall is also not able to absorb rainwater runoff into the soil. The use of natural materials for pavement construction is a must in supporting the achievement of green roads. This paper aims to obtain the most optimal mixture of standard design strengths using coconut fibers and coconut shell as a coarse aggregate with a ratio of 10%, 20%, 30%, 50%, 100% and the parameters used in this study are a compressive strength, permeability, and porosity resulting from the test object. The research methodology used refers to ACI 522.1-08, ACI 522R-10, ASTM C33-78. 2010, SNI 03-0691-1996, and SNI 03-2847-2002. Based on data processing of laboratory test results obtained from this study, the optimum value of the combination of 21% has a compressive strength of 17.1 MPa, permeability 0.5 cm/sec, and 23% porosity
