I am planning to install trench drain in front of my garage. The driveway to the garage is asphalt (less than 2" thick), and the space between the trench drain and asphalt will be filled with concrete. I am wondering whether the concrete will nicely meet the edge of the asphalt if I just pour concrete up to the asphalt without any form.
Keep in mind that this substance is not the number one material that you should use, but it will work in a pinch. For example, if you have a concrete driveway with cracks in it, the best solution would be to fill those cracks with new concrete or to even repave the driveway. There are even purpose-made concrete crack fillers.

Two separate measuring temperatures (25°C and 45°C) are used to evaluate the behavior of the mixture due to the change in the temperature. According to the findings of a case study, using a small percentage of polystyrene polymer lead to an increase in tensile strength, permitting polystyrene modified asphalt mixtures to be used in cold climates.
A tack coat restores the deteriorated asphalt and enhances the connection with the original pavement. A tack coat is a block of asphalt concrete, bitumen emulsion or asphalt cutback sprayed on a paved surface to support the binding during the building of asphalt concrete layers [28, 29]. 3.11. Rubberized asphalt (RA)
However, regardless of the differences in chemical composition, color and carbon content, all types of SF share a certain number of common, yet important physio chemical characteristics, which make them effective supplementary …

The binding characteristics of these materials generally increase subgrade load-bearing capacity. Typically, lime is used with highly plastic soils (plasticity index greater than 10), cement is used with less plastic soils (plasticity index less than 10) and emulsified asphalt can be …
A concrete driveway costs more to install than asphalt in most cases, and concrete takes much longer to cure before use. Still, concrete lasts longer and offers more customization than asphalt. Concrete also feels cool …
When these requirements are met, pouring asphalt over concrete can result in a refreshed surface that combines the solidity of concrete with the smooth finish of asphalt. Factors to consider before pouring concrete over asphalt. Before pouring concrete over asphalt, several factors need to be considered to ensure a successful outcome:
1. Introduction. Rutting, usually occurring in both asphalt layers and underlying unbound layers, is one of the main pavement distress modes [1], [2], [3], [4].For asphalt pavements where water is not allowed to pass through unbound layers, approximately 85 ∼ 95% of rutting accumulate in asphalt layers [5].Rutting usually appears in a form of surface …

Fiber-reinforced asphalt-concrete – A review. Sayyed Mahdi Abtahi, ... Sayyed Mahdi Hejazi, in Construction and Building Materials, 2010. Asphalt concrete (AC), a mixture of bitumen and aggregates, is a sensitive material compared to other configurations used in civil engineering. Therefore scientists and engineers are constantly trying to improve the performance of …
There are a number of reasons why you should seal the gap between concrete and asphalt. One of which is for aesthetic reasons, yes, but sealing the gap between concrete and asphalt is also important in order to help both your concrete and your asphalt last longer. Here's why you should seal the gap between concrete and asphalt. Aesthetic Appeal
The dynamic moduli have been recently introduced and effectively used to express the intrinsic behaviour of the viscoelasticity of an asphalt concrete material across a given range of temperatures and frequencies. Those can generally be represented in a form of the master curve. This study investigated the dynamic moduli of Western Australian (WA) asphalt mixes. …
A new driveway installation will last you between 30 and 50 years, so it's best not to rush into a decision about whether to use asphalt or concrete. Instead, take the time to weigh all the key factors, like your customization and maintenance preferences, budget, and climate, to find what might work best.
Potential Height and Drainage Issues: Adding an asphalt layer over concrete can increase the overall height of the pavement, which may lead to potential drainage problems. Consider how this extra height will affect door clearances …
