Abstract Due to the lack of research on applicability and optimization design low freezing point asphalt mixtures in specific environments, especially for harsh environments mountainous areas during cold winter high humidity other seasons, there is a significant engineering demand. This paper carries out study performance northern areas. Through comparative analysis mixture technologies road mi...

The D-optimal mixture experimental design was employed to optimize the melting point of natural lipstick based on pitaya (Hylocereus polyrhizus) seed oil. The influence of the main lipstick components-pitaya seed oil (10%-25% w/w), virgin coconut oil (25%-45% w/w), beeswax (5%-25% w/w), candelilla wax (1%-5% w/w) and carnauba wax (1%-5% w/w)-were investigated with respect to the melting point p...

Abstract Aggregate dispersion is one of the main diseases porous asphalt. Reasonable material composition can effectively reduce occurrence disease. In order to study how determine volume index and mechanical properties mixture from five aspects asphalt, asphalt oil film thickness, coarse aggregate, fiber filler, this paper selects different kinds materials additions, based on benchmark mix rat...

Carbide residue activated blast furnace slag is a relatively new kind of eco-friendly construction materials. This work addresses the design foamed lightweight concrete as road embankment material using such material. A statistical mixture approach was adopted to assess influence each ingredient well interaction between these on spreadability and compressive strength thus allowing design. The f...

Mixture experiments are experiments performed using ingredients whose proportions are restricted. This restriction may result in extremely small range in terms of the mixtures, causing difficulties in model fitting arising from ill-conditioning. The choice of model form is a very important factor in the numerical stability of the information matrix. In this paper, the intercept model is compare...
