求翻译：例如不断发展的预应力混凝土路面和交通部西部科技项目斜向预应力无缝水泥混凝土路面对混凝土的要求，应具有较高的抗弯拉强度和较低的弹性模量，从而避免路面施工过程中早期裂缝的发生。是什么意思？

The continuous development of prestressed concrete pavement and the Ministry of Transportation Western science and technology projects such as oblique prestressed seamless cement concrete pavement to face the requirements of the concrete should have a higher flexural strength and low modulus of elas

For example the prestressed concrete surfaces and the Western scientific and technological projects, traffic, the prestressed seamless portland cement concrete pavements, concrete requirements should be at a high flexural strength and a low down the elastic modulus, so as to avoid surface cracks ear

For example develops unceasingly west the pre-stressed coagulation earthen road pavement and the Ministry of Communications the technical project diagonal pre-stressed seamless cement concrete road facing the concrete request, should have high anti-pulls the intensity curved and the low elasticity c
