This is a shout-out to all Lae residents please petition the Lae City Provincial Administration to fix the ROADS.....Its getting so frustrating to see them continuously fill the potholes with gravel that washes away everytime it rains..Which it rains alot in lae, so we always end up driving in potholes....Please can we use the money which we pay those people filling the holes with gravel to fill them with Tar/Colta....
ENOUGH WITH THE BAD ROADS IN LAE..HONESTLY, CAN YOU FIX THE ROADS...Whats the use of getting road safety stickers when the road is not worthy to be driven on!!!

Frustrated driver

This Lae road has been an issue for decades old. That is true when can we have a better permanent road? Here in this country in South East Asia, I have observed that most of their roads are made of concrete cement as the bottom layer and the top is covered with bitumen to prevent the top layer from melting when the temperature reaches the highest of 40+ degrees in the summer season.
That weather differences in temperature is quite different in range from ours, but the point is the base is always solid for a long time.

Can there be a possibilty where civil engineers and land scientists do a study of the use of cement on roads in a Tropical counrty climate like Lae? I think Lae is very rich in limestone, the primary product for cement making.

Over to the Engineers and Scientist for any insights.

Lae's problem is not so much the heat but more the rain. When it rains the water tends to erode away the soil directly under the bitumen causing the it to crack and eventually break away entirely. Not only would Lae's roads benefit from at least 6 inches of concrete as a base but proper drainage also to stop the erosion. Regular funding would also help for upkeep.
