What is invert in drainage system?
The invert is the exact elevation of a drainage facility or pipe where the water is designed to flow. If a 2 foot dia. pipe crosses the road, one end of the pipe will be higher than the other, say 6 inches of fall. Say the high end (elevation measured at the end of the pipe at the flowline) is at elev. 325.00 The elev of the low end at the end flowline would be 324.50. 325.00 is the invert in 324.50 is the invert out
What is gatch road?
Gatch road, as seen in UAE and KSA desert areas is an improved sand road that has been lightly overlaid with a local limestone material called gatch. Teh result is a surface that is more resistant to blowing sand accumulation, and offers much better vehicle traction. Where a 4WD all-wheel vehicle is generally needed for sand track road travel, a gatch road can be passable with a 2WD vehicle. Gatch appears much like "caliche" as used in southern Texas roads.

How is a road built?
It is built using tarmac. First of all come the planning, preliminary surveying and the requirement and impact assessment phases. Inter-urban roads are the most complex. A number of criteria must be considered in the selection of a route, mainly based in the communities and geography to be traversed; areas of natural beauty, animal habitats, what will be the impact on people near to the new road; also, what kind of traffic will the road carry, will earthworks, bridges or tunnels be required and if so, what kind of equipment does the geology dictate; straightness of route must be traded against geographical elevation and the need to avoid too much blasting through solid rock and so forth. Then the route is planned on paper. Provision must be made for adequate drainage, protection of the area flanking the road and possibly the laying in of power for warning signs and lighting. Once the plan receives the requisite local government sign off and approval the work can start. at this stage surveyors will assist the road crew in laying out the route ("staking out"), and provide data for digging trenches and building embankments. Sources of water and material for the road bed must be located. The materials may come from a quarry or more often from a "borrow pit", in the latter case the road crew must ensure that the scar can be repaired back to its original green condition. Once this phase is complete the rock hardcore is laid. Rock is crushed, washed and screen filtered. There are various specifications for permissible lump size. The hardcore is laid incrementally and must be compacted thoroughly. Once the hardcore phase is completed the road can be tarred or concreted and the final road dressing and painting and the installation of safety features and road signs can take place.

How does a road surface dry after rain?
After rain, the road surface dries through a combination of evaporation and drainage. The heat from the sun helps to evaporate the water on the road, while any excess water is drained away through the road's surface or drainage systems. The rate of drying depends on factors like temperature, humidity, wind speed, and the porosity of the road surface.
Has Wellington Point Qld ever flooded?
No. Wellington Point, Queensland, is not in a flood prone area. Low-lying areas near the mangroves may be subject to king tides, but that is all. Years ago, before the new drainage systems went into the area, Birkdale Road and Anson Road were subject to flooding, but improved drainage has meant this has not occurred for at least 15 years, even with the torrential rain of December 2010 - January 2011.
What have drainage ditches alongside it?
rural road
Where does most hydroplaning occur?
Hydroplaning most commonly occurs in areas with standing water on the road, such as after heavy rainfall or in areas with poor drainage. It is more likely to happen at higher speeds, when tires can't displace water quickly enough to maintain contact with the road surface.
Does California highway patrol have jurisdiction in residential areas?
Yes. I think the county has to give the permission ( mine did) and when they do they can give a ticket anywhere on any road in the county.
why is the road is made slanted?
The main reason is drainage.
Why do roads have good drainage systems?
Although the entire road area drainage ditches, margins, road surface and medians must be constructed to prevent flooding, the normal effects of rain and other precipitation must be addressed as well. Both rain and melting ice and snow can erode potholes into the surface of the road, the freezing of water in road cracks can cause growth of the cracks and heaving of the road surface. This can be prevented by a good drainage system from the road surface. The other problem occurs when standing water is allowed to collect on the roads. This can lead to hydroplaning of car tyres with the loss of control of vehicles. Standing water can also freeze leading to a slippery and unsafe road surface.
How did the silk road affect economic systems?
The silk road connected two major points which were huge trading posts, without it neither areas would be as prosperous.
