Abstract The cement stabilized macadam base has excellent road performance and economy, it is widely used. However, also some shortcomings such as poor anti-scour ability insufficient frost resistance. To solve this problem, study uses Scanning Electron Microscope (SEM) to analyze the micro-morphology of specimen surface under four curing methods, namely moisturizing film, sack, polyethylene fi...

The durability of pavement subgrade materials is the most important indicator for judging their merits as well mechanical properties. material mainly reflected in its water stability, because actual environment, subjected to infiltration groundwater, immersion and washout pressure under concrete slab. a series damage caused by freeze-thaw cycles wet-dry due changes temperature. In view this, th...

One of the ways to increase strength and reliability building structures is use steel – fibre reinforced concrete. Steel concrete has significant advantages over conventional A high degree resistance cracking contributes an in such physical mechanical parameters as compressive, tensile bending strength, water resistance, frost chemical penetration. In concrete, used a reinforcing material, even...

Damage by late spring frost is a risk deciduous trees have to cope with in order to optimize the length of their growing season. The timing of spring phenological development plays a crucial role, not only at the species level, but also at the population and individual level, since fresh new leaves are especially vulnerable. For the pronounced late spring frost in May 2011 in Germany, we studie...

Austral summer frosts in the Andean highlands are ubiquitous throughout the crop cycle, causing yield losses. In spite of the existing warming trend, climate change models forecast high variability, including freezing temperatures. As the potato center of origin, the region has a rich biodiversity which includes a set of frost resistant genotypes. Four contrasting potato genotypes--representing...

This paper deals with an experimental study on the frosting phenomena using a fin bundle, which is an expanded model for the fins of the heat exchanger. The overall characteristics such as total frost mass, mass flux, pressure drop, sensible and latent heat fluxes and the local characteristics such as local temperature, local heat flux and local frost thickness were investigated under several e...

The effect of frost on the successful growth and quality of crops is well understood by growers as leading potentially to total harvest failure. Studying the frost phenomenon, especially in order to predict its occurrence has been the focus of numerous research projects and investigations. Frost prone areas are of particular concern. Grape growing for wine production is a specific area of vitic...
