When our family first moved into our home five years ago, the central heating and air unit were brand new. We never considered that there would be a time when it would not be operating as we wanted it to. When the time to buy a new unit came, we found that the available options were more diverse than we thought. It was all too confusing. After researching the different options, I decided to create this blog. My hope is that others who are faced with this decision can find easy-to-understand information that can aid in quickly making an informed decision.
Most road construction projects are on a tight schedule and must be completed as quickly as possible so that normal traffic patterns can resume and the inconvenience to travelers is minimized. At the same time, inclement weather and less-than-ideal temperatures can prevent paving crews from safely and properly finishing their work. Under what weather conditions can paving continue, and when should it be halted?
Paving Under Rainy Conditions
It can be challenging for paving crews to determine just what constitutes too much rain to continue work. Some light precipitation may not impact operations to the point of shut down, but steady rain can certainly cause problems with asphalt application and other paving work.
On the other hand, trucks that already have an asphalt mix prepared and are en route to the job site will waste what's been mixed if it is not applied within a time frame of a couple hours, depending on temperature and the exact mix of the asphalt material.
Risks of applying asphalt in the rain include:
Contractors may be able to pave some surfaces in mild inclement weather if that surface has been prepared properly and drains well. Applying asphalt to a stable base with a crushed aggregate that can drain away moisture may be possible even in light, steady rain. On the other hand, applying even a thin layer of asphalt as an overlay may cause problems.
Paving in Cooler Temperatures
It's very possible to apply asphalt in cooler temperatures, but care must be taken to ensure that the asphalt mix does not get too cool. If the mix isn't hot enough, you might see the following issues:
When in doubt because of weather conditions, road construction crews should wait -- even if it causes continued temporary delays, otherwise the integrity of the road surface could be compromised. For more information, contact companies like Lien Transportation Co.Share
