The overall goal of the project was to evaluate how the thermal mass of three different loadings of stone ballast and a heavy paver, all with relatively low solar reflectance, affects energy perfo rmance, especially compared to the highly reflective white roof. This p aper summarizes the results of the measurements for all three ye ars.
Sand and stone ballast is a mixture of sharp sand and small stones or gravel that is used to create a relatively coarse concrete mix. Primarily used alongside cement and water to secure fence posts or as a standalone sub-base for paths or sheds, Ballast is also popular as a base for patio slabs, footpaths and steps (although a more solid aggregate such as MOT Type 1 or scalpings …
Insulation level are specified by R-Value. R-Value is a measure of insulation's ability to resist heat traveling through it. The higher the R-Value the better the thermal performance of the insulation. The table below shows what levels of insulation are cost-effective for different climates and locations in the home.
Ballast is a mixture of sharp sand and small stones or gravel, used to make concrete for a variety of landscaping uses – from path edgings and shed bases to kerbs and securing fence posts. Why do boats need ballast? Ballast is used in ships to provide moment to resist the lateral forces on the hull.
In simple terms, R-values measure the effectiveness of insulation and a higher number represents more effective insulation. R-values are additive. For instance if you have a material with an R-value of 12 attached to another material with an R-value of 3, then both materials combined have an R-value of 15. R-value Units
In [25], 14 cyclic friction tests on railway ballast were conducted. Relatively sharp ballast tips were sheared over relatively flat ballast areas and the number of applied loading cycles ranged between 100 and 400. In all tests, a vertical load of 1 kN was applied and the total relative displacement was 2.4 mm.

RSI (R-value Système International ) is the metric equivalent. To convert the R-value of a specific thickness of a material to RSI, divide the R-Value by 5.67826. To convert RSI to R-value, multiply the RSI by 5.67826. For example, two inches of extruded polystyrene, with an R-value of 11, has an RSI of 1.93721. R-Value and Energy Codes

A complementary criterion, which is that the simulation should not be stopped unless the displacement of the pressing plates is over 0.2 mm (according to the test result, no ballast stone will be crushed by 0.2 mm), is added to ensure a smooth run of the simulation. 3.2. The constitutive model 3.2.1.
